You are a little soul bearing about a corpse, as Epictetus used to say.

Observe constantly that all things take place by change.

How easy it is to repel and release every impression which is troublesome and immediately to be tranquil.

Most of what we say and do is not essential. If you can eliminate it, you'll have more time, and more tranquillity. Ask yourself at every moment, 'Is this necessary?'

Always bear this in mind, that very little indeed is necessary for living a happy life.

He who does wrong does wrong against himself. He who acts unjustly acts unjustly to himself, because he makes himself bad.

Every instant of time... is a pinprick of eternity.
